摘要： 将玻碳电极置于0.1或0.2mol/LNaOH溶液中,采用恒电位(0.75VvsSCE)或电位扫描(0～0.75V)的方式氧化测定葡萄糖、蔗糖、果糖等碳水化合物,检测下限达1μg/mL,电极的重现性良好,使用寿命长,葡萄糖的检测范围为0.1～5×10-6mol/L.初步探讨了反应机理。

Abstract: The determination of carbohydrate, such as glucose, fructose, maltose, lactose, sucrose, glycerol etc. was carried out with glassy carbon electrode by constant potential oxidation (0. 75 Vvs. SCE) or potential sweep oxidation(0. 2-0. 75 V) in 0.1 or 0. 2 mol/L NaOH solution. The lowest detection limit is 1 μg/mL, Abetter repeatability and long useful lifetime are obtained. The detection range of glucose is 0.1-5×10-6mol/L. The response mechanism is discussed in this paper.
